A wooden tower tower in the shape of and in the pastel colors of the rainbow of the German brand Grimm's, consisting of 12 arches that fit and fit. The large rainbow tower is reversible, making it possible for many other towers. Then the tower can be 55 cm high. This involves finding a new equilibrium due to the movement of the arches. But there can also be a tunnel built or a dwarf cottage. This rainbow will always be a part of imaginative building and play.

The arches are made of linden wood, stained with water-based non-toxic pickles. This keeps the structure of the wood felt, it keeps breathing and feels fun and soft.
